IMPROVEMENT IN MACHINES FOR FITTING AXLE-SPINDLES T0 SKI-:INS 0F WAGONS.

Specification forming part of Letters Patent No. iflldl, dated October 9, 1866.

To all whom it may concern Beitknown that LConNnLIUs L. CAMPBELL, of Binghamton, in the county of Broome and State of New York, have invented a new and useful Improvement in a Machine for Fitting Spindles ot' Axle-Trees for `agons to Skeins or Thimbles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specitication, in which- Figure l is a perspective view; Fig. 2, a transverse vertical section, showing the gearreach. Fig. 3 represents the way or guideplate detached, Fig. t, a transverse vertical section of that end of the machine into which the reach is introduced.

Like letters represent like parts in all the gures.

The nature of my invention consists in titting the spindles or arms of axle-trees for wagons to cast iron skeins or thimbles by means of a revolving slide-cutter ruiming ob= liquely to the axis of its mandrel, dispensing with the use or control of a pattern, and so arranged that it can be made light and portlable and operated by hand, thus securing a more accurate tit and performing the operation in a more expeditious manner than by the` ordinary mode, which is by means of the drawshave and tile.

I construct my machine of the material usually used for similar purposes. I make the frame A ot' cast-iron, its'sides extending angularly from the annular collar O to near the end of the mandrel C. rlhis end of the frame should be left broad enough for the bearing ot' the journal on the end ofthe feed-screw E, as this screw runs parallel with and about three inches from the mandrel, revolving around it, and at the same time rotating upon its own axle by means of the crank which is attached to the internal gear driving wheel, as represented in Fig. 2

The pinion F is stationary and 'attached to the gear-standard Gr. The pinion H on the end oi' the feed-screw revolves with it around the mandrel, and is held in position by the arm I, which is keyed to said mandrel.

The revolving slide-cutter J is operated by a hinged nut, K, and, after turning t-he required distance, it is detached and drawn back. l

rlhe way or guide-plate L is attached to the frame, and so arranged as to give the required size and angle to the work by means of two projections or arms, m m, from the frame. In these arms I make a slot of sufficient length to graduate the guide-plate L to any required size and angle of the spindle. Said guideplate is secured in its position by means of screw-bolts.

The end of the machine into which the work is introduced is represented in Fig. et. The standard B has a iange ruiming around the circular opening, upon which the annular collar O and frame revolve. On the outside of said standard I make projections for set-screws for the purpose of centering and holding the work in its place. The working or gear end ot' the machine is supported by the standard G. The machine is now placed in position for operation by securing it to the bench.

Then I use my improvement, I iirst prepare the axle-tree by drawing a line through the center of the shaft from end to end. I then ascertain the caliber of the skein or thimble, and lay out the proper angle and size of the spindle, giving it the required gather 7 by throwing it a little out of line with the center of the shaft, commencing twelve inches (more or less) from each end. This variation is usually about one-eighth of an inch. The spindles are then prepared for turning by dressing them off to nearly the size and angle required. I then get the center on each end, and the work is ready for the machine. I now enter the end of the axle-tree through the annular collar O, and bring the center or the end in contact with the point ofthe mandrel O. I then adjust the set-screws to the work. I now set the way or guide-plate L to the proper angle and size of the spindle, then open the hinged nut K, and place the critter .I at the end ot' the spindle, and the machine is ready for operation,which is performed by means ot' the crank attached to the geardriving wheel. The feed screw is then caused to revolve around the mandrel, and at the same time to rotate on its own axle, by means of the stationary pinion F, and thus cont-rol the movement of the slide-cutter.

I do not claim the mere turning of the arms or spindles of axle-trees for Wagons to tit the box. l Neither do I elani the revolving taperin g' cutter-head.

Wha-t I claim, and desire to secure by Letters Patent, is-

The manner of fitting the arms or spindles of axle-trees for wagons to cast-iron skeins or thimbles by means of the revolving slide-cutter J in combination with the adjustable Way or guide-platerL, Fig. 3, the feed-screw E, and the hinged nut K, substantially as and for the purposes described.
